This study showed that a longer inoculation of probiotics will improve shrimp postlarvae growth and survival, and that a new technique developed for more accurately estimating postlarvae weight can significantly reduce the food that must be supplied.
Pacific white shrimp
Results of a study show that alternative, sustainable, plant-based protein sources such as improved soybean meal may potentially replace fishmeal in Pacific white shrimp diets.
Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems.
Inland shrimp culture has numerous advantages – improved biosecurity, lower cost of land and reduced conflicts with other users of common resources like land and water – and will continue to expand into new areas.
A study compared the bioavailability of crude protein and lipid from biofloc meals generated with an activated sludge system using two water sources: wastewater from shrimp experimental culture (BFL-W) and, artificially, using clean seawater (BFL-C).
Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases.
Selection for disease resistance has been used in breeding farm animals and can be a viable option to deal with white spot syndrome and acute hepatopancreatic necrosis disease in commercial shrimp culture. In trials, heritability for AHPND resistance was low,
Fenneropenaeus chinensis was the most important farmed shrimp species in China until 1995. Lessons learned from its development made China a pioneer, especially in shrimp larval production. Shrimp farmers must enhance their understanding of the interactions of farming activities with
In a study, “pre-fertilization” in the nursery phase of a biofloc system for shrimp was tested. The objective was to accelerate the biofloc formation to minimize ammonia concentrations, avoiding high peaks during culture.
